| Definition | A computer-controlled voltammetric measuring stand with built-in potentiostat and galvanostat. Applications include voltammetric trace analysis of metal ions and other substances, and Cyclic Voltammetric Stripping (CVS) for the determination of additives in electroplating baths. Operation of the 797 VA Computrace Stand follows the potentiostatic 3-electrode principle in which the voltage of the working mercury electrode is controlled by means of a virtually currentless Ag/AgCl reference electrode to the preset desired value and the current flows across a separate platinum auxiliary electrode. The pneumatically operated Multi-Mode Electrode (MME) can operate in Hanging Mercury Drop Electrode (HMDE), Dropping Mercury Electrode (DME), or Static Mercury Drop Electrode (SMDE) modes. A Rotating Disk Electrode with exchangeable electrode tips can be used in place of the MME. Additional accessories such as autosamplers and sample processors allow for full automation of analysis, and a range of accessory kits are available to extend the range of applications. The instrument supports over 220 analytical methods. | ||
